. i ADJUSTABLE CLIP FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 642,710, dated February 6, 1900.

Application filed October 5, 1898. Serial No. 692,678. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES J. PALMER, a citizen of the United States of America, residing at Cleveland, Ouyahoga county, State of Ohio, have invented certain new and useful Improvements in Adjustable Clips for Bicycles, of which the following is a specification in such full, clear, and exact terms as to enable any person skilled in the art to which it appertains to make, construct, and use the same.

The annexed drawings and the following description set forth in detail one mechanical form embodying the invention, such detail construction being but one of Various mechanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure I represents a side View of my improved adjustable clip applied to a bicycle-seat; Fig. II, an end view of the same; Fig. III, a crosssection on the line X X, Fig. I; Fig. IV, a modification of the construction adapted to double seatsprings; Fig. V, an end view of my device applied to a handle-bar; Fig. VI, a side view of a modification adapted to handle-bars, and Fig. VII a sectional detail view showing the worm-gear.

My device can be used for the adjustment of either the seat or handle-bar of a bicycle. The post 1 is inserted into the hollow tubing forming the frame and is secured therein by any suitable means. The end 2 of said post is flattened to form a head 3, which is circular in outline and provided with an eye 4. The circular portion of the head 3 is provided with a worm-gear 5. An adjustable block 7, adapted to be attached or secured to a bicycle-seat or handle-bar, is provided with depending ears 6, adapted to embrace the head. The lower ends of said ears are suitably curved and are rotatable in bearings 10, formed concentric therewith and arranged on both sides of the post immediately below the flattened portion. Perforations 8 are provided through the ears, and a pivot-bolt!) passes through said perforations and the eye in the head to secure the parts against displacement. A

web 11 is arranged between the ears and is provided with a perforation 12, forming a bearing for the worm 13, that is secured in said bearing by a nut 14 and a washer 15. The

opposite end of the worm is provided with a thumb screw or nut 16, longitudinally adjustable upon the worm, that has a bearing against the depending ears. Said worm is preferably provided with square threads and meshes with the gearteeth formed on the head. Knuckle-seats 17 are formed, one at each side of the adjusting-block, and two jaws 18 are hinged to said block by knuckles 19, fitting and rocking in the seats. A bolt 20 passes through the jaws and is provided with a nut 21, by means of which the jaws may be drawn together. The jaws have inwardlyprojecting flanges 22 at their upper free edges. In practice the seat-spring 23 is clamped by said jaws under the flanges of the same and may after suitable adjustment be secured in the jaws by means of the bolt and nut.

If two springs instead of a single one are used upon the bicycle-seat, grooves 24 are formed in the upper portion of the adjustingblock, as shown in Fig. IV, to receive said springs, which thus are securely clamped in place by the jaws and their flanges.

When my device is used in connection with a handle-bar, the jaws are enlarged and curved suitably to embrace said handle-bar and to securely hold the same, as shown in Fig. V. I may dispense with the jaws and enlarge the adjustingblock sufficiently to permit of a bore 25 being formed therein to receive the handle-bar, which can be secured in place by brazing or other suitable means, as illustrated in Fig.V. Instead of a straight post 1 an ordinary clip for engaging a T-shaped seat-post may be used, these two forms of construction being well-known equivalents. By this construct-ion an attachment secured to the adjustable block can be raised or lowered or moved backward and forward without dismounting from the bicycle. The worm is adj ustable in its bearing by means of the nut and thumb-screw, so that it will mesh accurately with the gear-teeth formed on the head, and thereby prevent rattling and hold the block securely in its adjusted position. The nut on the pivot-bolt provides an additional means for securing said block in its adjusted position. The entire Weight of the saddle is upon the bearings provided in the sides of the post,and both the pivot-bolt and the worm are relieved from strain. I am thus enabled of a worm meshing directly therewith. This construction requires a special form of handle-bar and is not suitable to the adjustment of a bicycle-seat. My improved device can be used with either a seat or handle-bar and does not require any special form or construction of these attachments. The adjustingblock is held firmly to its place by the ears or flanges, thereby securing additional rigidity and to a large extent preventing the rattling that results when the Worm operates directly upon the part to be adjusted.

What I claim is- The combination with a bicycle post, formed with a flattened head having a circular periphery provided with gear-teeth, and provided with' circular bearings below said flattened portion, of I an adjustable block adapted to be secured to a bicycle attachment, pivoted to rotate on said head, and provided with depending ears closely embracing said head and engaging with and rotatable in said bearings, a worm j ournaled in said block and engaging with said gear-teeth to rotate said block, and means for rigidly securing said block in its adjusted position, substantially as described.

In testimony whereof I sign this application in the presence of two witnesses,this 30th day of September, 1898.

CHARLES J. PALMER.
